The Sirui VH-10 Aluminum Professional Fluid Video Head is designed for today's photo/videographers. While this precision-machined aluminum video head weighs only 0.9kg (1.98lb), it can easily handle camera systems (camera, lens, grip, lights, etc.) weighing up to 6kg (13.2lb). And to keep everything level, it has a 2kg (4.4lb) built-in counterbalance system. The panning resistance is preset to provide amazingly smooth 360deg. pans and can be locked in position when you need precise framing. The Sirui designed fluid head tilting mechanism lets you steplessly dial in the amount of resistance you need - producing the smooth, professional looking movement you demand, whether you're working with a heavy or lightweight camera system. When the Tilt Control Knob has no resistance, the head can quickly be moved to the desired angle. The counterbalance mechanism helps to bring the head back to a neutral position when you tilt the head - this helps camera balance and reduces unsteady tilt sequences, even when no resistance is set. As you increase the resistance, or drag, you noticeably smooth out the look of your tilts. When you combine the smooth panning motion with properly selected drag for tilting, you will achieve a very fluid, professional look and feel to your videos.
